Description
technical field [0001] The invention belongs to the technical field of rail transit braking systems, and in particular relates to a locomotive braking individual control device. Background technique [0002] The braking system is a device or system capable of controlling the deceleration of the locomotive. It consists of two parts: the braking control system and the foundation braking device. A device that controls the foundation brake device to perform locomotive braking. A typical brake control system has the following functions: providing compressed air required for locomotive braking; providing control signals to the locomotive foundation braking device, thereby achieving braking and relief of the locomotive. To complete the above brake control functions, the brake system mainly includes the main air cylinder pipe, the general air joint pipe, the brake average pipe, the brake cylinder pipe, the action pipe, the brake (train) pipe, the brake cylinder pipe, the equalizer ...
